Dear Radsafe
The Feynman Lectures in Physics have been released in an online version by Cal Tech

On Friday Digital Einstein went live, courtesy of Princeton University Press.
I thought of Franz when I saw that a letter from Einstein to Madame Curie discussed “trolls” (or reptiles).

“…..In response to all this, Einstein praised Curie's work, and offered some time-tested advice for dealing with trolls. He preferred the evocative term "reptiles," but his succinct advice from a century ago still holds true today: "don't read that hogwash."”
